Low Float

Low-float stocks (<10M shares) are day-trader favourites for volatility. Squeezes happen when short interest is high + float is small, and forced covering sends price parabolic. They are also the easiest to manipulate (pump-and-dump). ### Why a small float moves so hard Nothing mystical happens. A fixed amount of buying pressure has to clear a much thinner book of resting sell orders, so the same order size walks price further. The scarcity is the volatility. That is the whole mechanism, and it cuts both ways with equal force on the way down. ### The halts are the part nobody plans for This is what separates people who have traded a runner from people who have read about one. Low-float names generally sit in **Tier 2** of the Limit Up-Limit Down mechanism (Tier 1 is the S&P 500, the Russell 1000 and certain ETPs). Per FINRA, the Tier 2 price band is 10% for stocks priced above $3.00, 20% for stocks priced from $0.75 up to and including $3.00, and for stocks below $0.75 it is the lesser of $0.15 or 75%. If the stock stays in its limit state for 15 seconds, trading is paused for five minutes. Read that again with a position on. A parabolic low-float stock can halt up, halt down, and halt again in a single session. During the halt you cannot exit. The reopen can print somewhere very different from where trading stopped. Beginners size for the stock's volatility and forget to size for the possibility that the market will not let them trade at all in the minutes that decide the outcome. ### The short-interest number you are using is stale Squeeze theses get built on short interest data that is far older than people assume. FINRA collects short interest positions **twice a month**, at the settlement date around the 15th and the last settlement day of the month, and the data is compiled and provided for publication on the **seventh business day after** the reporting settlement date. The short-interest figure you are quoting may be describing a market that no longer exists. ### What a real squeeze actually did The SEC staff report on early 2021 gives the only figures worth quoting. GameStop's short interest as a percent of float reached **122.97%** in January 2021, far above other meme names in the same period. Short interest can exceed 100% of the float because the same shares are lent and re-lent. But the same report reached a conclusion most retail traders never absorbed: staff found that buy volume stayed high after the direct effects of short covering would have waned, and concluded that it was positive sentiment, not the buying-to-cover, that sustained the weeks-long price appreciation of GameStop stock. A high short-interest figure is a condition, not a promise. It does not obligate anyone to buy your shares back from you. ### The two ways it turns on you - **Dilution.** The company whose tiny float created the move can sell more shares into that strength. The scarcity you are trading is not a fixed quantity, and the issuer has an obvious incentive to end it while the price is good. - **Manipulation.** The SEC's microcap investor bulletin is blunt: these stocks are historically less liquid and more thinly traded than the stocks of larger companies, and it says those factors make it easier for fraudsters to manipulate the price. A concentrated ownership base is, by definition, a low float. None of this says avoid studying them. It says: if you go near one, know the halt rules cold, treat the float and short-interest figures as lagging estimates, and accept that your exit may not exist at the moment you want it.
