Billionaire investor Stanley Druckenmiller made many moves in his Duquesne Family Office portfolio in the second quarter, slashing stocks while adding positions and boosting the overall holdings, SEC filings show.

At the end of the second quarter, the Duquesne Family Office portfolio was about $3.3 billion, up from $2.5 billion previously, a more than 30% jump.

Druckenmiller made a number of large additions to grow the portfolio. He boosted his Microsoft holding by nearly 63% during the quarter to roughly $366 million, now worth about 11% of the entire portfolio.

Part of Druckenmiller's strategy was to add large positions of companies hit hard by the coronavirus pandemic including JPMorgan Chase, Booking Holdings, and Starbucks. On the flip side, he also added shares of T-Mobile, and the SPDR S&P Biotech ETF, which have performed well amid the pandemic and ensuing recession.

During the second quarter, Druckenmiller also slashed positions of major technology companies including FAANG stocks. He sold about $235 million of Amazon shares, bringing the company to roughly 7% of the total portfolio. He also dumped sizeable positions of Netflix, Facebook, Google parent Alphabet, Workday, and Activision Blizzard.

Still, technology makes up about a quarter of the Duquesne Family Office portfolio, second only to consumer services companies, which make up nearly 30%. That's a change from the end of 2019, however, when technology was about half of the total portfolio.

In July, Druckenmiller said that he'd been "humbled" by the market's blistering recovery rally, and admitted that at the time he was up only 3% relative to the market's roughly 40% jump, effectively missing out on the surge.

Here are Druckenmiller's top 10 holdings as of the second quarter that ended in June, according to SEC filings and data from Hedge Follow.
