Medidata Solutions (NSDQ: MDSO), a leading provider of cloud-based research trial and recordkeeping software for pharmaceutical and biotech companies, sold off this morning after it delivered better than expected revenues and earnings. The stock initially rallied but eventually succumbed to aggressive selling. This is not an encouraging activity pattern so it’s time to get out while we still have some profits. The details are still sketchy, and even though the company has not delivered any bad news of late, it seems as if the guidance numbers may not have hit the spot. It’s also possible that we are starting to see the trickling down of the budget cuts and rising uncertainty about the election that I’ve been noting lately. I’ll have more about that in this Monday’s issue of Breakthrough Tech Weekly.
