A LOOK AT THE PAST 10 DAY PRICE PERFORMANCE
XBI had the lead, but Friday's sell-off dropped it to a 4% gain.-on the 10 day chart-
PJPis still up 6% over 10 days- SPY is up 1.85% over that same period.

Following last week's note of the XBI performance declining relative to PJP, SPY.
XBI swings - up and down- are wider than PJP or SPY.
Considering the 4% decline of the past 2 days, in proper context-
The move YTD is still up +20%.
Look at those declines relative to moves this year.
The debate in my mind- The 2 hr chart suggests i should have been stopped out today.
The Daily chart just today shows a 1st close under the ema.
If i pullback and look at XBI through a wider looking glass- on a daily chart over the last 3 months- Note that past similar closes under the ema have not meant that price would enter into a period of declines- Actually- there has only been 1 occurrence where price succeeded in putting in additional lower prices at the close-
The recent 6 week trend has been a relatively steady up hill climb- just today a Close below the EMA- I expect it will go lower- my present position size is $2,280.00/10 shares.
Where do i set a stop relative to this entry level?
If i applied the 2 hour chart, I would have been stopped out today- for a minor loss as price penetrated below my entry-
A stop under the low of a break of the 2 hr fast ema is very momentum based-
Now that I have a penetration/closing under the fast daily ema- I think enough is enough-
That is a tight stop-loss for my entry of $228.84- and price initially moved in my direction-
Now, the market is indicating that it may not agree- Nothing personal there
I will choose $226.50 - just under the swing low of today- as my stop. Loss would be $-23.40. if filled at the exact stop-loss
For those reading that don't bother to consider their trading this way: and never bothered to learned the math to calculate % - It didn't seem to have any application way back then.......school days.
Since we often trade in different amounts per each trade or position we hold- - to keep things relative- convert the trade amount into %. Percent. The calculation is simple-
Take the number of shares x the entry price
Bought 10 XBI @ $228.84 = 2,228.00 total investment amount.
Set my stop-loss -10 shares sell $226.50 = a 2.34 loss /share x 10 shares = - $23.40 loss
$23.40 loss divided by the initial entry value = 0.0105026..... Move the decimal 2 places to the right . round over any number in the 3rd place 5 or higher
The loss would represent -1.05026% or - 1.05%
Now- this is not a bad loss for an individual trade- if it does not exceed too much of a hit to your overall portfolio value.
Take the loss you might take on this trade $23.40 and divide it by the account total value.
In this case it would be $23.40/ $9700 = a 0.0024123.... or a very low portfolio loss of well under 1% = .24 or about one quarter of 1 percent.
By doing the percent conversion, you get a better sense of what is at Risk than just using Dollar amounts.
By using this calculation- I can see that i am Risking very little overall for the amount this trade represents to the overall portfolio value. Perhaps too little- and the stop is too tight-
Will a wider stop save the trade? end up with a win? No one knows- but a wider stop does not guarantee a positive result.
Most traders allow themselves to Risk too much on an individual trade-in the hopes of being Right- Or , they bet on too few positions within their account- too many eggs in one basket. and then -to make the trade work- they give it too much room to fail.
My XBI position is a good example- It represents almost 1/4 of my trading account value. Traders like myself with small accounts will find commission costs eat into their trade results. If one divides the account into 10 positions, each position is small, and the commissions to Buy and Sell make up a larger % of each position.
If a trader chooses to go with 5 positions- he has cut his commission costs in half-
A factor for small accounts-
If a trader has 4 active trades on and 1 cash position ready to trade, he has 80% of his portfolio in the market. Let's assume for the ease of the math-
an account value of 5,000.00. Each position = $1,000.00
The trader now has $4,000 in the market, with $1,000 cash primed to trade. the 4 trades stop out on market weakness, losing 5% on each position. (-$50.00 ea = 4 x -$50 = -$200.00)
The trader is now left with $4,800.00 cash.
The $200.00 that was lost only represents 2% of the overall trading account value.
This is an important concept to grasp- because the reality is that sometimes prices gap much lower on the open- black swan events, and the nominal 2% loss will actually end up being higher- likely a - 3-4% over a number of filled stops-
His each position allotment is now 4800/5 = $960.00 per equal position. His 5% max stop on any single position is now lower- he can only Risk $48.00 per trade-
Stock XYZ costs $50.00. He can Buy only 19 shares 19 x $50 = $950.00
His stop-loss of 5% means the stop must be less than 5% of his $50 entry price- or $-2.50 loss or a stop at $47.50.
A 5% loss on an individual trade is substantial, but common.
If a trader will use a position sizing formula to evaluate his risks and stay within that formula, he will survive to trade another day. If he suffers a series of market declines/losing trades, and the account value goes lower- the position sizing formula forces him to take smaller trades, and lesser Risks-
When the market turns around and starts to go back higher- His winning trades will increase the account value- allowing larger positions to be taken.
If one has a series of losing trades and loses 10% in the market- one needs to cut the position sizing % lower - Risking less in the 4 active trades -
I wanted to pass this on- because when the market gets choppy and non-trending- we often lose much more than we expect. When our trading results reflect that our approach is not as successful as it once may have been- it is time to get more conservative- protect the profits with taking smaller positions and reducing the downside Risk-
It is beter to step in late into
a trending market, than be early in a choppy one.
