This advice from Henry Clews is all you will need to make money.

But few gain sufficient experience in Wall Street to com-
mand success until they reach that period of life in which
they have one foot in the grave. When this time comes
these old veterans of the Street usually spend long intervals
of repose at their comfortable homes, and in times of panic,
which recur sometimes oftener than once a year, these old
fellows will be seen in Wall Street, hobbling down on their
canes to their brokers’ offices.

Then they always buy good stocks to the extent of their
bank balances, which have been permitted to accumulate for
just such an emergency. The panic usually rages until
enough of these cash purchases of stock is made to afford
a big “rake in.” When the panic has spent its force, these
old fellows, who have been resting judiciously on their oars
in expectation of the inevitable event, which usually returns
with the regularity of the seasons, quickly realize, deposit
their profits with their bankers, or the overplus thereof,
after purchasing more real estate that is oa the up grade,
for permanent investment, and retire for another season to
the quietude of their splendid homes and the bosoms of their
happy families.

What follows is very important in so many ways.

If young men had only the patience to watch the specu-
lative signs. of the times, as manifested in the periodical
egress of these old prophetic speculators from their shells
of security, they would make more money at these intervals
than by following up the slippery ” tips ” of the professional
“pointers” of the Stock Exchange all the year round, and
they would feel no necessity for hanging at the coat tails,
around the hotels, of those specious frauds, who pretend to
be deep in the councils of the big operators and of all the
new ” pools ” in process of formation. I say to the young
speculators, therefore, watch the ominous visits to the Street
of these old men. They are as certain to be seen on the eve
of a panic as spiders creeping stealthily and noiselessly
from their cobwebs just before rain. If you only wait to
see them purchase, then put up a fair margin for yourselves,
keep out of the u bucket shops “as well [as the “sample
rooms,” and only visit Delmonico’s for light lunch in busi-
ness hours, you can hardly fail to realize handsome profits
on your ventures.

Great stuff,indeed, written over a hundred plus years ago.
