Trading suspensions are a semi-regular occurrence on the PSE, as they are the “stick” that the rules give to the PSE to brute-force corporations into compliance for a wide range of non-compliant behaviors. Most of the PSE’s suspensions are for companies that have failed to submit their Annual or Quarterly Report (sometimes both), but there have been an increasing number of suspensions handed out for public float violations, which is a more serious problem (as we’ll get into). This post is all about suspensions, what they are, what they do, and why they’re trouble for investors. Major disclaimer: I suspect this post is of most interest to medium- and long-term investors (like me) who hold positions in the market for years at a time.
