可以理解为有大资金认为市场会暴跌而提前埋伏吗？

Caution is evident in ETF flows. The $1.2 billion ProShares Ultra VIX Short-Term Futures ETF -- the largest volatility-tracking fund -- posted roughly $263 million in inflows last week for its strongest weekly showing since 2016, and is on track to absorb an additional $159 million this week.
规模12亿美元的ProShares Ultra VIX短期期货ETF（最大的波动率追踪基金）上周录得约2.63亿美元的资金流入，为2016年以来最强劲的一周表现，本周有望吸收另外1.59亿美元。
I see!
Fed的钱去哪里了？是否可以继续印（写）？
Skepticism is evident in the still-sizable cohort of holdouts betting against the $278 billion SPDR S&P 500 ETF Trust, ticker SPY. Short interest as a percentage of shares outstanding on SPY -- a rough indicator of bearish bets on the fund -- is currently 5.1%, according to data from IHS Markit Ltd. Short-interest reached a near-record of 7.4% on March 3, and was as low as 1.2% at the beginning of 2020.
现在有140亿美元的资金在做空SPY， 相比疫情前大概只有30亿美元在空SPY。
作为比较，3月3日暴跌中的第一次小反弹时候有近200亿美元左右资金在做空SPY
While massive intervention on the part of the Federal Reserve has largely restored bond market functioning, JPMorgan Chase & Co. warns that equity liquidity levels are far from normal. Market depth for E-mini S&P 500 futures -- the ability to trade without substantially impacting prices -- remains about 60% below levels seen before March’s correction, analysts wrote in a note.
这段话可以理解为标普指数期货的ES的托盘资金合约数只有疫情前的40%
也就是说再次印证之前的推测，MM钱不够
