Tesla (TSLA – Free Report) kicked off the Q3 reporting cycle for the Magnificent 7 companies in style, with significant gains on the margins front raising hopes that competitive pressures may have started to ease. Tesla’s issues have always been unique, not providing any read-through to the five Mag 7 peers that are coming out with Q3 results this week.This week takes us into the heart of the Q3 earnings season, with more than 800 companies reporting results, including 168 S&P 500 members. Of the Mag 7 members, we have Alphabet (GOOGL – Free Report) on Tuesday, October 29^th, Meta (META – Free Report) , and Microsoft (MSFT – Free Report) on Wednesday, October 30^th, Amazon (AMZN – Free Report) and Apple (AAPL – Free Report) on Thursday, October 31^st.The bounce in Tesla shares has more than made up for the market’s disappointment with the Robo taxi announcement. But the stock is still the Mag 7 laggard this year, as the chart below shows.Image Source: Zacks Investment Research
Tesla’s margin gains are particularly notable in this quarterly release, but it is perhaps premature to assume that the margin pressures are now behind them. There is some talk that maybe a bigger proportion of this quarter’s deliveries came from the high-margin Shanghai factory. Part of the gains may also have resulted from production tax credits related to Tesla’s battery production.Should Tesla’s Q3 margin gains prove durable, then we can reasonably expect extrapolation of the same into the coming quarters. The table below shows net margins for the group, with Tesla’s 2024 Q3 net margins of 8.7% up from 5.8% in the preceding period and 7.9% in the year-earlier period.Image Source: Zacks Investment Research
Alphabet shares were down in response to the last earnings report on July 23^rd even though the company had handily beaten consensus EPS and revenue estimates. If we look at the stock’s performance since July 22^nd, the day before the Q2 earnings release, Alphabet shares are down -9.3%, which compares to a +1.1% gain for the Zacks Tech sector and a +3.9% gain for the S&P 500 index.Given this performance despite strong results, we can reasonably opine that the market will remain unimpressed with this report as well unless management can make a compelling case for its ever-rising AI-centric spending plans. Investors’ worries increased due to management’s comment during the Q2 earnings call that the risk on the capex question was more about under-investing than the alternative.The capex question isn’t restricted to Alphabet alone, as Microsoft, Amazon, and Meta also face the same issue. But the issue is particularly central for Alphabet as many in the market see AI as risking the company’s search monopoly. This likely explains why Alphabet shares have lagged Microsoft and Amazon over the last three months, as the chart below shows.Image Source: Zacks Investment Research

As you can see, the group is expected to bring in +16.9% more earnings in Q3 relative to the same period last year on +13.3% higher revenues.The chart below shows the group’s earnings and revenue growth on an annual basis.Image Source: Zacks Investment Research
As we all know by now, the group’s phenomenal boost in 2021 partly reflected pulled forward demand from future periods that got primarily adjusted in 2022. The group returned to the ‘regular/normal’ growth model last year, and the trend is expected to continue this year and beyond.
