Is stock churning happening here?

I have a stock that has a P/E ratio of 1.3.Seems very low. I've noticed that the stock will go up 3-4 points then settle back to its starting position. Thios has occured several times in the last couple of months. About 72% of the stock is owned by institutional investors.My question is this:

Do the institutional investors with their high speed computers churn this stock e.g. selling it when it increases several points then repurchasing it when it falls back?
