What Charlie Munger and Grandma Ruth taught this money manager. His portfolio is up 50% this year.

Tesla
TSLA,
+1.33%,
Apple
AAPL,
+2.11%,
Amazon.com
AMZN,
+1.41%
and Alphabet
GOOGL,
+1.33%
are his top four stocks due to “durable competitive advantages,” but have also seen rapid growth and were cheap when purchased.

“We own 21 companies and I think it’s important to point out that we’re not just tech,” he said, rattling off other picks like Nike
NKE,
+0.23%,
Visa
V,
+0.07%
and Mastercard
MA,
+0.11%
and Hershey
HSY,
-1.41%.

And non-tech holdings Accenture
ACN,
-0.18%
and No. 5 stock Costco
COST,
+1.05%
are both up double digits this year. He owns the latter partly due to insights from Berkshire Hathaway’s
BRK.B,
-0.46%
late vice chairman Charlie Munger, who he dined with in 2018.

Tsai recalls the Costco enthusiast and “mentor” telling him that paying 25 time pretax multiple for the retailer “wasn’t unreasonable at all.”

Munger also told him this: Sometimes to make money, you need to “sit on your ass.” And “you don’t want to do too much, but when a good opportunity comes around the corner, you want to swing hard.”

“In other words, you want to put a lot of capital to work. That’s been our approach,” said Tsai, whose portfolio has returned 7.43% annualized net of fees, versus 6.87% for the S&P 500 index
SPX
since its 2000 inception. And during that rough dot-com start, Tsai made money by investing in “hated old economy” stocks such as auto supplier Genuine Parts
GPC,
-2.40%
and Berkshire Hathaway, which lost half of its value at the time.

He also credits generations of knowledge. From his father — the late Gerald Tsai Jr. who pioneered momentum trading and started Fidelity Investments’ first aggressive growth fund in 1958 — he learned to “position yourself with the wind at your back.”

His grandmother Ruth Tsai, the first woman floor trader on the Shanghai Stock Exchange and who “made a killing” until the arrival of Japanese troops in 1941, passed down wisdom about preserving capital during bear markets. One of her favorite sayings: “When the tide goes out 10 feet, a large boat and a small boat both go out 10 feet.”

He sees Amazon
AMZN,
+1.41%,
Alphabet and Microsoft
MSFT,
+0.92%
as “equivalent of the railroads during the time of Rockefeller and Cornelius Vanderbilt” by controlling the cloud. Their services operate the infrastructure that enabled the cloud, with lots of data still on those servers. “We are in the early stages of this cloud evolution, so I like those names,” he said.

As for AI, Tsai says he missed out on Nvidia
NVDA,
+2.33%
by not being “smart enough to understand that company early on.” But he’s betting on those “selling the picks and shovels” of the AI revolution, like Amazon
AMZN,
+1.41%,
Alphabet and Microsoft
MSFT,
+0.92%,
who can all “piggyback” on that.

And Tesla is also a leading AI company, thanks to its “data and ability to analyze data over its Dojo computing network. And Tesla’s combining that during a period when the whole world will continue to move toward electric vehicles.”

Tsai also draws parallels between Tesla and Costco, who he notes have both created competitive economic “moats.” And as they gain scale, they increase profit and margins but pass that back to the consumer via lower prices, hence generating demand.

Drawing on Munger and others, he says a big blind spot he sees among investors now is overlooking what they own. “Think about companies that you already know well, let them compound for you, let them work for you, instead of just jumping to the next shiny thing.”

The chart

The S&P 500 is sitting 4% away from getting back to prior highs from early 2022, but on a total return basis — those generated by dividends and price changes — “the market is knocking on the door of new record highs,” says Bespoke Investment.

Their chart shows the S&P 500 total return index is 1.1% away from its prior record high from 1/3/22.  “In addition to nearing its prior highs, the pattern of the S&P 500 looks a lot like a cup and handle which technicians consider to be a bullish formation,” says Bespoke.
