Two documents dated Thursday, 12 November, answer the same question at two scales, and their units do not convert. NVIDIA (the chipmaker) said Jensen Huang had resigned as chief executive officer (CEO), effective at once, with the finance chief taking the same job in the interim [1]. The shares fell as much as 14% that day [2]. Hours earlier the Internal Revenue Service (IRS) had set the 2027 defined-contribution cap at $75,000 [3]. Your room in that cap comes out of a salary and never out of a share certificate. It does not hold stock, and no deposit schedule could have seen Thursday coming.

At a glance

  • The shift: Washington raised the 2027 retirement cap as a founder’s exit repriced his shares.
  • The number: $75,000, the 2027 cap on plan additions for you and your employer [3].
  • The risk: Set by salary, so it holds pay, not a position.

The Cap Is Written in Salary

The order of events matters. The board had already brought in outside lawyers for an internal inquiry, and the shares had slid through the two sessions before the news [4]. The resignation came on Thursday and took effect at once; the firm kept its 17 November earnings date [1].

What the IRS put out that same morning was a cap, and its shape is the whole argument. Under section 415(c) of the tax code, a year’s additions may not top the lesser of the dollar figure or 100 percent of your pay [5]. An addition counts what your employer puts in, what you put in, and any forfeited money [5]. Pay goes in; a tax-free balance comes out. Nothing in the section mentions shares. A share certificate is not a deposit and never enters the sum [6].

A 6 percent match on a $200,000 salary claims $12,000 of the cap before you save a dollar. That sum is mine, and the inputs sit in this sentence. What is left, after your own deposits and the match, is the after-tax space a mega-backdoor Roth turns into Roth money inside the plan [3]. It is a real container. It is also sized by a paycheck.

I read the two figures side by side and kept waiting for one to touch the other. They do not. The cap climbs with inflation by design. The shares fell as much as 14% in an afternoon because a board met.

By the numbers

  • $25,500 deferral cap: The 2027 limit on your own 401(k) deposits, before any employer match [3].
  • $8,500 catch-up: The extra a saver 50 or older may add in 2027, outside that cap entirely [9].
  • $470 billion: The value NVIDIA shed over the two sessions before the resignation [4].

What a Plan Can’t Schedule

The rule behind a planned sale is Rule 10b5-1, and its clock is why a bad week cannot be handled once it starts. A director or officer who adopts a plan may not trade until the later of 90 days after adoption or two business days after the quarter’s results come out, and never more than 120 days out [7]. Everyone else waits 30 days [7]. Change the amount, the price, or the timing, and the rule treats the plan as ended. A new one starts its clock from zero [7].

The one exception that helps at a vest is sell-to-cover, a setup that sells only the shares needed for the tax withheld on a vesting award and leaves the insider no say over timing [7]. It is the plain version of cutting the bet, and it is the only one still open on the morning a board meets. Anything larger has to be set in a calm week, months early. A trading blackout bars insiders from acting in the week they would most want to.

The other half of the call is the hold-versus-sell sum for restricted stock units (RSUs), and it is the part most plan papers leave to you. The container is not common either: 36 percent of Vanguard’s defined-contribution plans allowed in-plan Roth conversions in 2025, and 10 percent offered automatic ones [8]. I would want to know which of those features a plan actually grants, and I would want the answer before a blackout, not during one.

The catch

The honest version of Thursday is quieter than the headline. The shares closed 4.3% lower, so a holder who did nothing lost part of an afternoon, while anyone who sold at the open sold at the day’s worst price [2]. None of this makes a planned sale free. It turns a risk that cannot be dated into a tax that can, and the tax is real.

The cap has a fair claim of its own. Money in a plan grows without a yearly drag, and the after-tax space is one of the few places a six-figure earner can put a dollar the code will not tax again [3]. A resignation after 33 years is also close to a once-in-a-career event, though the slide before it was not: that ran two sessions on a report, before any board vote [4].

I could be wrong about where the weight belongs, though the unit mismatch is the whole story. A container sized by salary cannot manage a position sized by shares. The yearly limit news is not a plan to cut the bet.
