NEW YORK ( ETF Expert) -- A do-it-yourself investor would be wise to track institutional money. Are there surprising, or not so surprising, moves that advisers make via their block trades?Often, the activity will give you the heads-up if advisers like myself are on their way to a party before the rowdier guests arrive. Similarly, tracking block allocations might tell you whether or not advisers, asset managers and/or hedge fund gurus are leaving an enthusiastic celebration early to watch digitally recorded episodes of Breaking Bad. For example, PowerShares Emerging Market Sovereign Debt ( PCY) has caused more portfolio pain than portfolio pleasure in 2013. Fortunately, for clients who had owned PCY, we minimized loss with stop-limit orders during the May-June rout of higher-yielding income assets. PCY had served us so well since 2009. Shortly after Federal Reserve Chairman Ben Bernanke's taper talk on May 22, however, our mechanical and unemotional sell discipline removed the asset from our accounts. Then, in September, the 10-year yield tickled 3%, while the Federal Reserve backtracked on its anticipated policy change. Ever since, yield sensitive assets have been gaining ground. In fact, for the past few days, PCY has picked up more than 100 million in assets on twice the average trading volume.
