The Bull Market Turns Four — a Weekend Guide to the Volatile Week That Ended With the Nasdaq Back on Top

Somewhere in the middle of October 2022, the current bull market was born, and this week it turned four. Its birthday present arrived on schedule: a week of genuine volatility — the kind that has defined this market all autumn — that resolved into a Friday rally leaving the S&P 500 at 7,811.54, the Dow at 51,654.90, and the Nasdaq at 27,366.17, back above the record 27,244.28 it set on September 22 before the yield-spike selloff knocked it sideways. The VIX closed at 14.84, down 3.7% on the day, and the 10-year Treasury yield — the variable that has refused to cooperate all month — eased back to 5.24%. It was the week, as one live blog put it, that stocks rallied to cap a volatile run just as earnings season nears.

The averages make the week look serene. It was anything but underneath. Palantir hit an all-time high with a 5.17% surge as Wall Street warmed to its next phase of growth — a notable outcome for a stock Michael Burry has been publicly short. AT&T fell 9.81% in a single session after SpaceX’s Starlink picked up spectrum assets, a competitive escalation analysts say undermines the carriers’ best argument. Moderna jumped 14.21% to a four-year high on a planned national cancer-vaccine effort. And Apple reportedly cut iPhone 18 Pro component orders after a $100 price hike — the same memory-cost squeeze this blog first flagged in June arriving, finally, at the cash register.

A four-year-old bull, violent underneath and calm on top, heading into earnings season. Here are the three lessons the week handed down, and the checks to run against your own portfolio before Monday opens them.

Lesson one: at four, a bull market runs on earnings, not momentum

Year-one bulls are recovery trades. Year-four bulls have to be paid for. This one has now absorbed a 10-year yield above 5% for a month, a Federal Reserve that hiked in September with more on the table, mortgage rates near 7.6%, a payrolls print of just 29,000, and the most public short-selling campaign against the AI trade in years — and its birthday week still ended with the Nasdaq back in record territory. The reason is the one this blog keeps returning to: the earnings are real. Micron’s $133 billion fiscal year and $85 billion of net income were not narratives; they were receipts. What history says about fifth years is worth knowing — they have happened before, and they have ended before — but the practical reading is narrower: at this age, the index rises when companies deliver and rotates violently when they might not. Which makes the calendar, not the mood, the thing to watch. Q3 earnings season opens within days, and after a quarter in which the AI trade absorbed every bearish catalyst thrown at it, guidance is the next referee.

Lesson two: a calm index can hide a violent portfolio

An investor who only glanced at the VIX — 14.84, barely above its month’s low — would conclude nothing happened this week. Tell that to an AT&T shareholder who watched nearly a tenth of the position vanish on a spectrum headline, or to Palantir’s holders watching the opposite. Starlink’s move into spectrum is the week’s clearest case study: the index did not move because of it, but the telecom sector repriced a decade of assumptions in one session. Apple’s reported order cuts carry the same lesson in slower motion — the memory shortage that minted record profits at Micron is now showing up as a $100 iPhone price hike and softening demand at the world’s largest consumer company. One supply chain, two opposite portfolios. The lesson for anyone holding a diversified index plus a handful of individual winners: your personal volatility is not the VIX. It is the volatility of what you actually own, and it only becomes visible when you look at positions instead of averages.

Lesson three: the next referee is guidance, and it arrives Monday

For a month, this blog has described a market that shrugs — every bearish catalyst absorbed, every selloff refused. Shrugging is behavior, not protection, and the thing that finally forces a verdict is never the macro headline; it is guidance. Earnings season starts within days, and it arrives with an unusual amount of homework already done: the Street knows memory is pricing a downturn by fiscal 2028, Apple is evidence the shortage is transmitting to consumers, and Palantir’s all-time high is a bet that the AI build-out’s next phase is software, not just silicon. Q3 prints will either extend the receipt-driven bull into year five or hand the bears their first confirmed crack. You cannot control which. You can control whether the reaction is planned.

The pre-earnings-season checklist

The routine is the one this guide keeps returning to because it is the only part of the process you fully control: see every account at once. InvestSheet syncs positions from Robinhood, Fidelity, Schwab, and 35+ other brokerages into a single Google Sheet with live formulas, so the whole portfolio — including the winners that have grown the fastest and the laggards nobody checks — shows up in one place:

Four checks, ten minutes, one sheet. The bull market’s fifth year will bring the same package this month already delivered: a calm average doing something violent underneath, a supply chain repricing in real time, and a referee arriving on a schedule. The investors who do well in year five will not be the ones who predicted it. They will be the ones whose caps, cash, and cost basis were already written down before the first guidance disappointment — because the sheet said so, in numbers, while the market was closed.
