Healthcare remains a top bet for the closely followed investor

Stanley Druckenmiller's Duquesne Family Office is leaning a little more into tech lately.

Earlier this year, Stanley Druckenmiller spoke of diversifying his portfolio and giving artificial intelligence less of a starring role, but his most recent quarterly holdings show that may be easier said than done.

Druckenmiller's investment firm, the Duquesne Family Office, continued to maintain cell-free DNA testing group Natera $(NTRA)$ as his biggest holding - a 16% chunk - in the second quarter, according to a filing with the Securities and Exchange Commission released on Friday.

For the first time in at least two years, however, technology occupied the second and third positions in his portfolio, based on data from Whale Wisdom. Those were a 5.4% position in contract chip maker Taiwan Semiconductor Manufacturing $(TSM)$ and a 4.4% position in analog semiconductor maker STMicroelectronics $(STM)$, both of which he added to. TSM's stock is up 40% this year, while STMicro's has seen a 109% gain.

Druckenmiller ditched smaller positions in Broadcom $(AVGO)$ and hot memory name Micron $(MU)$ in the second quarter, which would have helped avoid sharp selloffs that came in June and July.

Druckenmiller, who was formerly George Soros's right-hand man, is a closely followed investor known for a series of prescient calls, although he spoke a couple of years ago about his regret over selling Nvidia (NVDA) too soon.

The investment firm built more than a dozen smaller new positions in tech stocks, plus a new stake in Alphabet $(GOOGL)$ worth 2.3% of the portfolio, and added options calls on Tesla $(TSLA)$ and Meta $(META)$ worth 1% and 0.5%, respectively. An options call, which gives the buyer the right to purchase the underlying security at a particular price within a specified time frame, was also added on the iShares Russell 2000 exchange-traded fund IWM, which is up 24% this year.

There were also more than a dozen smaller new positions representing less than 1% of the portfolio in tech stocks such as Advanced Micro Devices $(AMD)$ and Palo Alto Networks (PANW).

A position in Amazon (AMZN) - at No. 9 - under consumer discretionary was boosted slightly to a 2.5% share of the fund.

The No. 5 position was a call option on the iShares MSCI Brazil exchange-traded fund EWZ. Druckenmiller's Brazil bet has cooled some since April but has paid off for him previously.

And: Investor dubbed 'AI stock god' had 56% of his funds in these two stocks before the July blow-up
