OPINION
In this ERISA action for breach of fiduciary duty, plaintiff Ann Taylor appeals the district court’s dismissal of her complaint for lack of subject-matter jurisdiction. In the event that Taylor’s appeal is successful, defendants KeyCorp and numerous individually named fiduciaries (hereinafter referred to as “defendants”) cross-appeal the district court’s denial of their motion to dismiss. In addition, Anthony S. Lobasso appeals the denial of his motion to intervene. Upon review, we affirm the dismissal of Taylor’s complaint for lack of subject-matter jurisdiction and the denial of Lobasso’s motion to intervene. We do not address the denial of defendants’ motion to dismiss because it is moot.
I.
Taylor filed this action on behalf of herself and a class of similarly-situated participants and beneficiaries of the KeyCorp 401(k) Savings Plan (the “Plan”) on August 11, 2008. She brought this class action pursuant to §§ 409 and 502 of the Employee Retirement Income Security Act (“ERISA”), 29 U.S.C. §§ 1109, 1132, against defendants KeyCorp and numerous individually named fiduciaries of the Plan. On January 7, 2009, the district court ordered that Taylor’s lawsuit be consolidated with a similar action, and thereafter, Taylor and plaintiff Elaine Klamert filed a consolidated class action complaint. The consolidated complaint defines the proposed class as “[a]ll persons who were participants in or beneficiaries of the Plan whose Plan accounts included investments in KeyCorp common stock ... at any time between December 31, 2006[,] and the present[.]”
Taylor and Klamert assert five claims. In Count I, plaintiffs allege that defendants breached their fiduciary duties by failing to prudently manage the Plan’s investment in KeyCorp securities. In Count II, plaintiffs allege that defendants failed to adequately inform participants about the true risk of investing in KeyCorp stock. In Count III, plaintiffs allege that certain defendants breached their fiduciary duties by failing to adequately monitor the management and administration of Plan assets. In Count IV, plaintiffs allege that certain defendants failed to avoid impermissible conflicts of interest. Finally, in Count V, plaintiffs allege that certain defendants are liable for the breaches of fiduciary duty committed by their co-fiduciaries.
Following consolidation, defendants moved to dismiss the complaint pursuant to Federal Rule of Civil Procedure 12(b)(6). The district court denied the motion. Thereafter, defendants moved to dismiss for lack of subject-matter jurisdiction pursuant to Federal Rule of Civil Procedure 12(b)(1), arguing that neither Taylor nor Klamert sustained an “actual injury” sufficient to confer Article III standing. In response, plaintiffs’ counsel asserted that Taylor did sustain an injury, forfeiting any argument with regard to Klamert. *612 Upon review, the district court held that Taylor did not suffer actual injury because she had “benefitted” from the alleged breaches of fiduciary duty, which allowed her to sell the majority of her KeyCorp holdings at an inflated price. Final judgment was entered on August 12, 2010.
On September 10, 2010, Anthony S. Lo-basso moved to intervene as a plaintiff and class representative under Federal Rule of Civil Procedure 24. Three days later, on September 13, 2010, plaintiffs filed their notice of appeal. Based upon the district court’s entry of final judgment, Lobasso’s motion was denied. Thereafter, defendants filed a cross-appeal challenging the denial of their motion to dismiss, and Lo-basso filed an appeal of the denial of his motion to intervene.

We review a district court’s dismissal pursuant to Federal Rule of Civil Procedure 12(b)(1) de novo.

IV.
Taylor asserts that during the class period, defendants breached their fiduciary duties by failing to disclose and/or misrepresenting KeyCorp’s inappropriate lending and tax practices. This, she alleges, caused KeyCorp stock to become unduly risky and artificially inflated. 1 However, in order to have standing to pursue this lawsuit, Taylor must establish that she was actually injured by defendants’ alleged conduct. This she has failed to do.
*613 Taylor’s relevant trading history was summarized by the district court as follows:
[A]s of December 31, 2006, the beginning of the class period, [Taylor] owned 1,678.32 units of the Key stock fund. Ms. Taylor sold all of those units on January 11, 2007, when Key stock was trading at over $37 per share. Key stock reached its peak price of $39.90 per share on February 22, 2007. Following her sale of Key stock in January, 2007, Ms. Taylor never purchased another unit in the Key stock fund. She did acquire an additional 387.31 units in Key stock through Key’s matching program. On February 22, 2008, she sold 268.01 of those units and sold the remainder of her 119.30 units of Key stock fund on June 25, 2008. Overall, Ms. Taylor sold her Key stock for more money than she actually paid for it, earning a net profit of $6,317.
This trading history reveals that Taylor sold over 80% of her KeyCorp holdings at a time she claims the stock was artificially inflated. Accordingly, if the allegations in the complaint are true, Taylor sold the majority of her KeyCorp holdings for more money than it was worth, thereby benefit-ting from defendants’ alleged breach of fiduciary duty.
Under similar circumstances, several courts have found plaintiffs to be without Article III standing, holding that plaintiffs suffer no “actual injury” when they benefit from alleged artificial inflation.
See Brovm v. Medtronic, Inc.,
If ... [the] stock was artificially inflated, then any Plan participants who purchased company stock during the period of inflation overpaid for the stock units and would have a claim to benefits equal to the amount overpaid. A Plan participant who sold company stock during that same period, on the other hand, received “too much” for the units and benefitted [from] the inflation accordingly.
In re Boston Scientific,
Supreme Court precedent also supports this rationale. In
Dura Pharmaceuticals, Inc. v. Broudo,
*614 Taylor disputes that out-of-pocket loss is an appropriate measure of her injury, suggesting that we use an alternative-investment theory. Specifically, Taylor claims that she would have made more money on her investments if her holdings had been transferred away from KeyCorp stock and placed in the S & P 500 index. We hold that such a measure of damages is not appropriate in this case.
When a plaintiff alleges that the withholding of information affected share prices, “the appropriate measure of damages [is] the difference between the investment as taken and the investment as it would have been if not tainted by withheld information.”
Brown,
In advocating for an alternative-investment measure of loss, Taylor relies on several cases providing that plaintiffs are “entitled to a remedy which will put [them] in the position in which [they] would have been if the trustee had not committed the breach.”

Warren v. Soc’y Nat’l Bank,
V.
Taylor and the Department of Labor (as amicus curiae) assert that, even if the cor *615 rect measure of her injury is out-of-pocket loss, Taylor has still established “actual injury” sufficient to confer Article III standing because she suffered a loss on the KeyCorp stock she obtained through Key-Corp’s matching program. Specifically, they argue that, even if Taylor benefitted from the alleged artificial inflation with regard to her January 2007 sale, the shares she obtained thereafter were purchased at an inflated price and sold at a loss. The question is, then, whether Taylor’s gains and losses during the class period must be netted to determine whether she suffered actual injury. We hold that netting is required in this case.
The fiduciary duties outlined in ERISA draw upon the common law of trusts.
See Varity Corp. v. Howe,
Here, Taylor asserts that defendants beached their fiduciary duties by concealing KeyCorp’s “true financial and operating condition,” rendering KeyCorp stock an imprudent investment throughout the class period. She does not allege separate breaches causing separate damages. Accordingly, all gains and losses during the class period, attributable to one course of conduct, should be netted. 5 When such netting is done, it is clear that Taylor has suffered no actual injury. Accordingly, Taylor does not have standing to pursue this lawsuit. 6
*616 VI.
On September 10, 2010, Lobasso moved to intervene as a plaintiff and class representative. Three days later, Taylor filed her notice of appeal. The district court thereafter denied Lobasso’s motion to intervene, holding that because the underlying action was terminated, the motion was untimely.
“We may affirm the district court’s judgment on any ground supported by the record, including on a basis not mentioned in the district court’s opinion.”
Westfield v. Fed. Republic of Ger.,
“The filing of a notice of appeal is an event of jurisdictional significance-it confers jurisdiction on the court of appeals and divests the district court of its control over those aspects of the case involved in the appeal.”
Griggs v. Provident Consumer Disc. Co.,
Lobasso argues that, unlike
Bowling,
the motion to intervene in this case was filed
before
the notice of appeal, thereby allowing the court to consider the motion. In addressing this question of first impression, we find the reasoning of
Roe v. Town of Highland,
In this case, Lobasso did not file an emergency motion, nor did his counsel (the same counsel representing Taylor) request additional time in which to file a notice of appeal. In addition, there is nothing in the record indicating why Lobasso waited until September 2010 to intervene. Once the Rule 12(b)(1) motion was filed, Lobasso was on notice that Taylor may not be an adequate class representative. Therefore, a precautionary motion to intervene could have been filed.
Lobasso relies on a handful of cases that allowed a motion to intervene to be decided after final judgment was entered. However, in most of these cases, no notice of appeal was filed to divest the district court of jurisdiction.
See United Airlines, Inc. v. McDonald,
In the case at bar, the district court was not given sufficient opportunity to address the motion to intervene prior to the filing of the notice of appeal. Once such notice was filed, the district court was without jurisdiction to address the motion. Accordingly, the district court did not err in denying Lobasso’s motion to intervene. 12
VII.
For the foregoing reasons, we affirm the district court’s order dismissing Taylor’s complaint for lack of subject-matter jurisdiction. In addition, we affirm the denial of Lobasso’s motion to intervene. We decline to address all other issues on appeal as moot.
Notes
. For purposes of establishing standing, Taylor seeks to recast her complaint as one not alleging artificial inflation. This attempt is disingenuous at best. The complaint clearly alleges that KeyCorp stock was artificially inflated. ("During the Class Period the market price of KeyCorp common stock was artificially inflated due to the concealment of KeyCorp’s true financial and operating condition[.]"). Taylor cannot avoid the consequences of this allegation at this juncture.
. Similarly, several courts have found plaintiffs to be without Article III standing when the alleged breaches of fiduciary duty resulted in no economic harm.
See Harley v. Minn. Mining & Mfg. Co.,
. Taylor contends that there is a difference between “actual injury” for purposes of Article III standing and damages. We agree. However, "[i]n most cases ... a plaintiff's standing tracks [her] cause of action. That is, the question whether [s]he has a cognizable injury sufficient to confer standing is closely bound up with the question of whether and how the law will grant [her] relief.”
Braden v.
*614
Wal-Mart Stores, Inc.,
. In asserting entitlement to an alternative-investment measure of loss, Taylor also relies on a footnote in
LaRue v. DeWolff, Boberg & Associates, Inc.,
. Taylor further asserts that even if the correct measure of actual injury is out-of-pocket losses, and even if her gains and losses are netted, there is a question of fact regarding whether her gains in the beginning of the class period were greater than her losses at the end of the class period. This argument, however, was not placed before the district court and is therefore forfeited.
See Blue Cross & Blue Shield Mut. of Ohio v. Blue Cross & Blue Shield Ass'n,
. The Department of Labor asserts that Taylor has standing to pursue her claims, even in the absence of injury, simply because defendants breached duties owed to her pursuant to ERISA. This argument, however, was not raised by the parties in their appellate briefs. Accordingly, we will not consider this issue.
Cellnet Commons, Inc. v. FCC,
. Entry of final judgment, alone, is not a basis upon which to deny a motion to intervene.
See United Airlines, Inc. v. McDonald,
. Following the filing of a notice to appeal, the district court does retain jurisdiction to enforce the judgment,
City of Cookeville, Tenn. v. Upper Cumberland Elec. Membership Corp., 484

Inland Bulk Transfer Co. v. Cummins Engine Co.,
.Following entry of final judgment, the parties have 30 days in which to file a notice of appeal. Fed. R.App. P. 4(a)(1)(A).
. Lobasso asserts that the district court had discretion to retain jurisdiction over pending motions, citing
Dixon v. Clem,
. The Third Circuit has held a district court to have jurisdiction to consider a motion to intervene after a notice of appeal is filed.
Halderman v. Pennhurst State Sch. & Hosp.,
.While the district court did not have jurisdiction to address the motion to intervene, this court may, in its discretion, remand the matter back to the district court to address the motion.
