In the first few months of the year, a trading desk rumor emerged that even as institutional traders dumped stocks and retail investors piled into ETFs, a "mystery" central bank was quietly bidding up risk assets by aggressively buying stocks. And no, it was not the BOJ: while the Japanese Central Bank's interventions in the stock market are familiar to all by now, and as we reported last night on sessions when the "the BoJ comes in big, the average return on the [Nikkei] is about 14 basis points higher" with Nomura calculating that "the BoJ has provided a cumulative boost to the Nikkei of about 1,400 points"...

... the one thing about the BOJ is that it keeps its interventions local, and tends to mostly prop up Japanese stocks, whether the Nikkei 225 or the Topix.

The answer was revealed on Friday when the hedge fund known as the "Swiss National Bank" posted its latest 13-F holdings. What it showed is that, as rumored, the Swiss National Bank had gone on a record buying spree in the first quarter, boosting its total equity holdings to an all time high $80.4 billion, up $17 billion from the $63.4 billion at the end of 2016, the biggest quarterly increase in "AUM" in history.

Yet while we are long beyond the point of debating the central bank intervention in equity markets (we do want to remind readers that until several years ago, it was considered "fake news" to even mention it, and those who accused central bankers of manipulating stock markets were said to be paranoid tinfoil basement dwellers), we want to point out that unlike the BOJ, which at least keeps its capital markets distortion local, the SNB, which likewise creates money out of thin air (then sells it for dollars in an attempt to keep the Swiss franc depressed) is actively resulting in even greater price distortions in the US.

While we doubt this will be investigated with stocks are at all time highs, we look forward to the Congressional hearings after the crash when the scapegoating and fingerpointing begins, and everyone is "stunned" to learn that central banks were responsible for blowing the biggest asset bubble the world has ever seen by directly buying stocks.

What else did the SNB reveal in its 13F? Two main things.

First, its top 20 holdings are as shown in the following chart. The central bank was clearly not shy in adding to its top positions, especially the top position.

And while we don't know if Warren Buffett was actively frontrunning the SNB when he more than doubled his AAPL stake in Q1, making him a top 5 holder of the tech giant, a look at the SNB's holdings of AAPL stock which increased from 15 to 18.9 million shares, shows why the Nasdaq - as observed earlier in the day by Goldman Sachs - just refuses to drop hitting daily all time highs.

The chart above may also explain why Goldman is bullish on the Nasdaq 100: after all, when a central bank can and does create money out of thin air, then splurges on the company that accounts for 12% of the weight in the Nasdaq, pushing the Nasdaq and all indices higher, what is the point of even talking about "risk"?
