Shares of Polyrizon Ltd ( PLRZ ) surged 223% to 82 cents Friday afternoon, following a reversal in reverse stock split plans from Thursday.

What To Know: On Thursday morning, the company had announced a 1-for-10 reverse stock split, intended to consolidate every ten shares into one, with trading on a post-split basis to begin May 5. The move originally aimed to bolster the company's per-share price, a common tactic to meet minimum listing requirements.

However, late Thursday, Polyrizon ( PLRZ ) canceled the reverse split, stating it would not proceed with the plan as previously disclosed.

The change has triggered a flurry of speculative trading during Friday’s session, as the company provided no further explanation for the decision, leaving investors to interpret the implications.

Friday’s volatility also highlights the sensitivity of small-cap stocks to corporate actions and the potential impact of sudden governance shifts.

How To Buy PLRZ Stock

Besides going to a brokerage platform to purchase a share – or fractional share – of stock, you can also gain access to shares either by buying an exchange traded fund (ETF) that holds the stock itself, or by allocating yourself to a strategy in your 401(k) that would seek to acquire shares in a mutual fund or other instrument.

For example, in Polyrizon’s case, it is in the Health Care sector. An ETF will likely hold shares in many liquid and large companies that help track that sector, allowing an investor to gain exposure to the trends within that segment.
