Oracle announces its figures for FY18 this afternoon after the market closes. Until then, they're in a quiet period. Announcing or having big layoffs would telegraph the results, so they're not about to do that.
Watch the stock price in the aftermarket, at 4:10 ET this afternoon. If you see red, the amount of layoffs depends on how much red, and they will likely happen before the July 4 holiday. If you see green, there probably won't be many layoffs.
