Crypto Purge Averted, But MSCI World ETF’s Record Rally Faces Overbought Headwinds

MSCI abandons plan to exclude companies with large digital asset treasuries, sparing MicroStrategy. The iShares MSCI World ETF nears 52-week high with extreme overbought RSI of 94.6.

MSCI has decided not to exclude companies holding large digital asset treasuries from its flagship world indices, a move that spares the likes of MicroStrategy and other crypto-correlated heavyweights from potential forced selling. The index provider had floated a rule that would have barred firms where digital assets make up at least 50% of total holdings, but after a consultation period that concluded on January 6, 2026, it abandoned the plan. The reprieve is not indefinite, however: MSCI has frozen new additions and size migrations for so-called Digital Asset Treasury Companies (DATCos), and it is launching a broader consultation on how to treat non-operating companies in the future.

The decision arrives as the iShares MSCI World ETF, which tracks the same broad index, closed Friday at $204.93 — exactly its 52-week high. The fund has climbed 34.2% from its March 30 low, and over the past month it has added between 4.15% and 5.70% depending on the measurement window. Yet the euphoria is matched by extreme technical readings. The relative strength index stands at 94.6, deep in overbought territory, and the ETF has pierced the upper Bollinger Band, a pattern that often precedes a pause or pullback.

The quarterly rebalancing that took effect on May 29 introduced three new names: Medline A, MasTec, and TechnipFMC. Those additions reflect shifts in U.S. market capitalisation and keep the index fresh. The rebalancing also marked the first application of a refined free-float rounding methodology, which adjusted rounding intervals and buffers across liquidity categories, increasing the portfolio turnover rate. A further free-float adjustment is scheduled for June 1, which could nudge weights for individual stocks and subtly alter sector and country allocations.

Nvidia continues to dominate the top holdings with a 6.36% weight, followed by Apple at 4.86%, Microsoft at 3.21%, Amazon at 2.85%, and Alphabet (Class A) at 2.59%. The technology sector overall accounts for 30.4% of the portfolio, with financials a distant second at 15.6%. Within tech, Micron Technology was among the recent standout performers, riding the AI wave that has lifted the entire space. Despite the global diversification across 1,308 positions in 23 developed markets, the fund’s short-term momentum remains closely tied to the U.S. tech narrative.

The latest rebalancing also tightened the index’s liquidity requirements. MSCI excluded securities from frontier markets such as Bangladesh due to persistent market-access issues, ensuring the ETF stays focused on accessible, liquid developed-market stocks. The fund uses physical sampling replication to mirror the MSCI World Index, which tracks large- and mid-cap companies in developed economies. Total expenses come to 0.24% per year, with semi-annual dividend distributions.

Technical indicators paint a mixed picture for the coming week. The MACD turned positive on May 28, a signal that historically has led to further gains for the ETF over the following month. Against that, the extreme RSI reading and the Bollinger Band breakout argue for caution. The annualised 30-day volatility sits at 11.54%, modest for an equity ETF but enough to produce sudden swings. The combination of a record high, a packed index calendar, and unresolved questions about DATCos means investors face a delicate balance between momentum and overextension.
