AUM figures shown are calculated by summing the reported market value of all positions in SEC 13F-HR filings — not the fund's actual assets under management.
- Excludes cash, bonds, private equity, short positions, and foreign-listed stocks not required to be reported.
- For PUT and CALL options, the reported Value is the notional value of the underlying shares — not the option premium paid. This significantly overstates the actual capital at risk.
- Actual fund AUM is typically higher and includes strategies, instruments, and positions that never appear in a 13F.
- 13F filings cover institutional managers with ≥$100M in 13F securities. Positions reflect end-of-quarter holdings, disclosed up to 45 days after the period ends.

(MKSI) further emphasizes the fund's focus on technology and industrial technology sectors, aligning with a strategy that seeks to capitalize on sectors driving innovation and technological advancements.</p> <p>The recent portfolio adjustments by Whale Rock Capital Management signal a strategic shift and refinement of their investment thesis. The closure of positions in Semtech Corp. (SMTC), MercadoLibre Inc. (MELI), and Nu Holdings Ltd. (NU), alongside significant reductions in Ciena Corp. (CIEN) and MongoDB Inc. (MDB), suggests a move away from certain tech and emerging market plays, possibly due to perceived risks or underperformance. Conversely, the substantial increases in positions such as Kenvue Inc.
