IRM is an incredibly stable stock. Even currently as the market is falling IRM is green on the day. However, if you analyze the chart carefully you will be able to see that about a week prior to the dividend ex-date. The stock will fall. It's not a might fall. For the last few years, the stock has gone down in the span of 1-2 weeks. It has also been overbought according to the RSI Chart and is due for a pullback. It is currently pushing higher even when the market is red. I'm no expert, but it has dropped up to 18%. The risk-reward ratio seems pretty solid.
