My next big call (under $1) (Ad)

Crypto traders have a name for this month... Uptober. Since 2013, Bitcoin has closed October higher in 10 of 13 years, with an average gain close to 19%. And this year may be setting up better than most. Bitcoin just strung together its first positive August and September since at least 2013. Historically, when September finished green, October followed with a gain four times out of five. History isn't a guarantee. But I pay attention when the calendar and the momentum line up.tc pixel

Short selling SAIA is an investing strategy that aims to generate trading profit from Saia as its price is falling. SAIA shares are trading up $10.64 today. To short a stock, an investor borrows shares, sells them and buys the shares back on the public market later to return it to the lender. Short sellers are betting that a stock will decline in price. If the stock does drop after selling, the short seller buys it back at a lower price and returns it to the lender. The difference between the sell price and the buy price is the trader's profit.

A short squeeze for Saia occurs when it has a large amount of short interest and its stock increases in price. This forces short sellers to cover their short interest positions by buying actual shares of SAIA, which in turn drives the price of the stock up even further.

Short interest is typically published by a stock exchange once per month. However, NASDAQ publishes a report for U.S. stocks, including SAIA, twice per month. The most recent reporting period available is September, 15 2026.

Understanding short interest metrics can help you assess how traders are positioning around a stock like SAIA:

  • Shares Sold Short: The total number of shares that have been sold by short sellers but have not yet been covered or closed out. A high number may indicate bearish sentiment.
  • Short Float: The percentage of a company’s publicly available shares (or "float") that are sold short. A higher short float suggests a greater portion of the stock is being bet against.
  • Days to Cover (Short Interest Ratio): This estimates how many days it would take short sellers to cover their positions, based on average daily trading volume. Higher values can signal potential for a short squeeze if buying pressure increases.

These metrics are often used by traders to gauge sentiment, volatility risk, and the potential for price movements based on short covering activity.
