LNAS - Can it be a Long Term Hold?

Want to pick HC brains about holding LNAS as a long term as opposed to a trading vehicle. Like many, I am a believer in the long term success of the Nasdaq. Chart shows what the last ten years looks like, but DYOR. I am a believer that the stocks in Nasdaq are well selected and have shown over time that this is the case. E.g. avoidance of financials and miners.
So...... if this is the chart of the Nasdaq unleveraged imagine what the chart would look like if it was leveraged at 2.6 times (LNAS roughly).
I realize that losses are multiplied the same as gains but if one takes a long term position on the index, what are the specific dangers/risks of utilizing LNAS as a long term hold rather than the Nasdaq itself.



Interested in the community thoughts on the strategy.
