I am constantly looking for “tells” in the market, little nuggets of information that no one else notices, but give me a huge trading advantage.

Well, there is a big one out there right now. The bottom feeders are pouring into San Francisco commercial real estate, taking advantage of valuations that sometimes reach negative numbers. Owners are walking away from buildings, mailing in the keys, and going into default rather than keeping up mortgage payments. What’s worse is refinancing at today’s lofty rates. That’s what you would expect with a 36% vacancy rate.

The message for you traders is loud and clear. You should be picking up the highest quality technology growth stocks on every substantial dip, such as Microsoft (MSFT), Amazon (AMZN), Alphabet (GOOGL), Meta (META), and NVIDIA (NVDA). For they all know some things that you don’t. Their businesses are about to triple, if not quadruple over the coming decade thanks to AI. For every abandoned building out there are 200 new AI start-ups taking advantage of today’s bargain basement rates, and ALL of them use the services of the five companies above.

Technology stocks, which now account for an eye-popping 30% of stock market capitalization, will make up more than half of the market within ten years, much of that through stock price appreciation. And they are all racing to lock up the office space with which to do that….now.

San Francisco office rents reached a record pre-pandemic as the continued growth of tech — now turbocharged by nearly $100 billion in new capital raised in a series of initial public offerings — met a severe space crunch.

Asking rents rose to a staggering $84.16 per square foot annually for the newest and highest quality offices in the central business district, and citywide asking rents for such spaces, known as Class A, were up over 9% from the prior year. The citywide office vacancy rate was 5.5% in June, down from 7.4% a year ago.

In addition, local Bay Area home prices could get a turbocharger by the fall, when interest rates are expected to start falling.

San Francisco companies that have gone public continue to grow by leaps and bounds. Pinterest (PINS), Slack (WORK), and Uber (UBER) also signed office leases this year, with room for thousands of new employees.

Tech companies Autodesk (ADSK) and Glassdoor also signed deals at 50 Beale St. in the spring. In a sign of the city’s rapidly changing economy, old-line construction firm Bechtel and Blue Shield, the legacy health insurer, are both moving out of 50 Beale St. Sensor maker Samsara, software firm Workday (WDAY), and Sony’s (SNE) PlayStation video game division also expanded.

Globally, San Francisco has the seventh-highest rents in prime buildings. It’s still behind financial powerhouses Hong Kong, London, New York, Beijing, Tokyo, and New Delhi (San Francisco’s average office rents beat out New York.)

Only a handful of new office projects are being built, and future supply is further constrained by San Francisco’s Proposition M, which limits the amount of office space that can be approved each year. That is creating a steadily worsening structural shortage. Only two large office projects are under construction without tenant commitments.

Suddenly, it’s Not Crowded in San Francisco
