The stock price tripled today, but your account didn’t gain a penny—so don’t get excited just yet, and don’t rush to complain either.
BlackRock’s spot Ethereum ETF (ETHA) officially took effect today (October 6) with a 1-for-3 reverse split: every 3 shares are consolidated into 1, and the share price rose from about $14 to about $42.
But this is just a math trick: the fund hasn’t changed its ETH holdings at all, and your total assets are worth exactly the same. Your brokerage will consolidate the shares automatically, so there’s nothing you need to do.
So what’s BlackRock’s goal? Bloomberg ETF analyst Eric Balchunas put it plainly: to reduce trading costs. ETHA is down about 40% year to date. With its share price at a low level of around $14, the bid-ask spread makes up a larger proportion of the price, pushing trading costs to 7 basis points. After the reverse split, with shares at $42, that can drop to around 2 basis points.
The takeaway: this is a perfect example of the hidden tax retail investors are most likely to overlook. Commissions are visible; the drag from bid-ask spreads isn’t—but over the long run, it can still eat away at your returns. If institutions think even 7 basis points is too expensive and are using a tool as drastic as a reverse split to bring costs down, retail investors should take a closer look at their own trading frictions. Frequent short-term trades and wide spreads on low-priced coins are the real hidden killers of returns. As for ETH itself, the split doesn’t affect its fundamentals. What’s really worth watching is the outlook for staking yields and ETF flows—don’t mistake a “threefold increase in the share price” for a bull-market signal.
Data as of: 2026-10-06 00:00 UTC (the effective date of the reverse split; the share price of around $14 is from before the SEC announcement in August)
