Stock

I’ve been noticing an interesting trend with my employee stock purchase plan over the last two years. Each time that stock is allocated, usually sometime in the middle of a given month, the stock is more or less at the same price that it’s been at for the last couple weeks (sometimes it’s a bit higher... which sucks!) But each time, without fail, the day after the stock is allocated, the stock drops in price by $0.50 - $1.00. What the hell is going on here!? Is there some kind of conspiracy to rip us off of our employee stock benefit?
