Yes trends are our friend until the unexpected bend at the end takes us by surpise.
PLS is currently tracking well ... but how long is a piece of string ?

A fool, a fool, I met a fool i' th' forest,A motley fool.
A miserable world!

As I do live by food, I met a fool,
Who laid him down and basked him in the sun
And railed on Lady Fortune in good terms,In good set terms, and yet a motley fool.

“Good morrow, fool,” quoth I.
“No, sir,” quoth he,
“Call me not ‘fool’ till heaven hath sent me fortune.

And then he drew a dial from his poke
And, looking on it with lackluster eye,
Says very wisely, “It is ten o'clock.
Thus we may see,” quoth he, “how the world wags.

'Tis but an hour ago since it was nine,
And after one hour more ’twill be eleven.

And so from hour to hour we ripe and ripe,
And then from hour to hour we rot and rot,
And thereby hangs a tale.”

When I did hear
The motley fool thus moral on the time
My lungs began to crow like chanticleer
That fools should be so deep-contemplative,
And I did laugh sans intermission
