The defining story at BRK.A right now is not where short sellers have moved, but what the CEO did with his own money in March — and what it signals about conviction inside Omaha.
In early March, Greg Abel made a cluster of open-market purchases totalling roughly $6.9 million across ten separate transactions. All were executed on a single day, March 4, at prices ranging from $725,210 to $733,100 per share. The cumulative net insider position over the past 90 days is 21 Class A shares, representing approximately $15.3 million of net buying. For a stock at $723,821, these are deliberate, public bets. Abel's first significant buying cluster since assuming the CEO role is a visible signal of alignment — the kind of move long-only holders tend to view as meaningful at the leadership-transition stage of any major franchise.
The institutional picture reinforces that the register is dominated by long-term holders rather than active traders. Warren Buffett personally holds 13.6% of the float — effectively anchoring the register. Vanguard added around 1,900 shares in the most recent reporting period and BlackRock added 4,265, both consistent with index-driven flows rather than a directional call. The Bill & Melinda Gates Foundation trimmed 1,573 shares, but its remaining stake of 12,944 A-shares is still substantial. This is a shareholder base built for the long hold, not the short flip.
That character is reflected almost perfectly in the short data. At just 0.075% of free float, short interest in BRK.A is economically negligible. A 29% week-on-week increase in shares short sounds dramatic until you realise the absolute level has moved from roughly 142 to 171 shares — tiny relative to the $1 trillion-plus market cap. Borrow availability is extremely loose; utilisation barely moves through any trading period, consistent with a deep, low-demand lending pool. The cost to borrow has fluctuated noisily — reaching 0.77% intraday last week before settling back to 0.21% — but neither reading reflects genuine short-squeeze dynamics. The ORTEX short score of 26.6, ranking in the 89th short-score-rank percentile (meaning few stocks have a lower short score), confirms that this is one of the least aggressively shorted names in the universe.
Analyst coverage is thin and the dominant voice has been UBS's Brian Meredith, who maintains a Buy rating and trimmed his target modestly to $854,596 on May 4 — still nearly 18% above Friday's close of $723,821. The consensus mean target also sits around $759,000, implying roughly 5% return potential to the average estimate. Keefe, Bruyette & Woods continues to run an Underperform, with a target of $695,000 set back in November 2025 — below where the stock trades today. Valuation sits at a P/E of 23.7x and a price-to-book of 1.39x. The P/B has expanded about 0.05x over the past 30 days, consistent with the mild positive price drift. EPS momentum scores are soft — ranked in the 19th percentile on 30-day EPS momentum and just the 9th on the 90-day measure — suggesting forward-estimate revisions are not a near-term catalyst.
The most recent earnings event triggered only a 1.1% one-day decline, followed by a 1.5% five-day recovery. That is classic Berkshire price behaviour: limited single-day volatility around results, with the market more focused on the conglomerate's balance sheet health and capital allocation posture than any given quarterly print. With no confirmed next earnings event on the calendar yet, the near-term focus returns to Abel's early signals on capital deployment — specifically whether the $334 billion cash pile reported in early May begins to shrink through acquisitions or buybacks under new management.
The stock is up about 0.9% on the week and roughly 1% on the month, a narrow positive drift that has brought it back close to where it began the year. The RSI-14 at 56.8 suggests neither overbought nor oversold conditions. What to watch in the weeks ahead is any commentary on buybacks — Berkshire repurchased zero stock in Q1 2026, according to recent filings — and whether Abel's personal buying marks the beginning of a broader signal of confidence in the franchise at current prices.
