Getty Images Apple joins other Silicon Valley giants in reporting earnings this week, along with drug makers and Starbucks.On Halloween week, most companies reporting earnings are waiting until after Tuesday’s spookiness to provide their figures, but that just makes Wednesday and Thursday more crowded with reports, led by Apple Inc., Facebook Inc. and Tesla Inc. Here’s what to expect: Wednesday is set to be a massive day, with auto-maker Tesla TSLA, -0.25% reporting after the bell. Freewheeling Chief Executive Elon Musk often hosts memorable earnings calls, unlike most of his relatively staid peers. Investors will be looking closely at the company’s Model 3 production numbers, which have fallen short of what the company needs to hit to meet the lofty targets Musk has set.

Investors are expecting nearly $10 billion in revenue for its third quarter and will closely monitor what executives say the company is doing to combat decelerating revenue from aging products, like its news feed, and efforts to suck in additional ad dollars via new products, such as video.

Investors will be looking for any and all clues about the new $1,000 iPhone X sales, potential supply issues and details about the new iPhone 8s, which went on sale just before the end of the third quarter. But some analysts say that the supply issues with the iPhone X may actually help the company in the long run. Apple AAPL, +0.59% is one of three components of the Dow Jones Industrial Average DJIA, -0.36% set to report this week, along with Pfizer on Tuesday morning and DowDuPont on Thursday.

EA, +0.59% is one of the few companies willing to release results on Halloween, kicking off the busy week for Silicon Valley companies Tuesday. Rounding out Wednesday’s big tech day are gadget makers Fitbit Inc. FIT, +0.66% and GoPro Inc. GPRO, +3.40% . Investors will be eyeing Fitbit’s new smartwatch, which the company has set up to compete with the new Series 3 watch from Apple. But reviews suggest the company still has a ways to go with its hardware, and since the new watch went on sale Oct. 1, guidance will be the thing investors watch closely.via
