Industrials have logged a solid week thus far, with SPDR Industrials (NYSEArca: XLI) rising nearly 2% and closing at $37.03 a share on Tuesday, just a shade under its 50 day moving average.

We have seen notable inflows as well in XLI, with more than $350 million entering the fund via creations in recent days, which is more than 10% of the assets outstanding in the ETF. Having a heavy weighting to GE (11.15% of the index), the top five holdings in XLI are as follows: GE (11.15%), UPS (5.59%), UTX (5.56%), CAT (5.21%), and MMM (4.50%).

GE is expected to release earnings later this week, prior to the market open on 4/20. Also, it is worth noting that UPS is also the third largest holding in the Dow Jones Transportation Average Index, with an 8.50% weighting currently.

In the Domestic U.S. Industrials space in terms of ETFs, there are a number of options available in addition to XLI, which tracks an S&P based sector index. Vanguard Industrials (NYSEArca: VIS) tracks an MSCI Industrials based index, while iShares Dow Jones U.S. Industrial Sector (NYSEArca: IYJ) tracks, as its name suggests, a Dow Jones index.

Guggenheim S&P 500 Equal Weighted Industrial (NYSEArca: RGI) tracks the same index as XLI, only the portfolio holdings are equal weighted and rebalanced on a monthly basis so as to keep them in line. XLI as one might expect, is a market capitalization weighted index calculated by a stock’s price multiplied by its shares outstanding, or “float.”
