What is the margin requirement when shorting a stock under $5.00? Are these stocks marginable?

As of August 2, 2024, the new margin requirement for short positions that are low priced is as follows:

Stocks priced below $5.00 = $5.00 per share margin requirement

For example:

Short 1,000 NXL @ $1.50

Margin requirement = 1,000 x $5 = $5,000

Short 5,000 SILO @ $2.16

Margin requirement = 5,000 x $5 = $25,000

Please also be aware that margin requirements may change daily and overnight due to various factors including, but not limited to, volatility, low float, and percentage of insider holdings.
