Every reference with a DOI in the deposited reference list resolved to a known
work in Crossref or DataCite at the dated check, and none carried a retraction,
withdrawal, or removal notice.
6 without a DOI — not checked. A reference
deposited without a DOI is never matched by title or guessed at; it stays outside the checked
set, and this line discloses that.

no DOI — not checkedOur spoofing traders can be classified into two groups: spoofing traders who were not day traders (57.8%) and spoofing traders who were day traders (42.2%). Panel B shows descriptive statistics on extra profit for these two groups. Panel C shows descriptive statistics on extra profit for day traders; the left column represents the day traders who were also spoofers, whereas the right column represents all day traders, regardless of whether they were spoofers. Day trading is defined as the purchase and sale of the same stock by the same investor on the same day. Korea imposes a tax of 30 basis points on the sale of securities paid by the seller. Trading fees during our data period consisted of a fee of approximately one basis point to the exchange, and about seven basis points to online brokers on executed buy and sell orders. Thus, for example, each day-trading strategy costs 46 basis points. All statistics in Part 1 are measured without clustering by day. All statistics in Part 2 are measured by the Fama and MacBeth (1973) approach: average all the observations on a given day, then assume independence across days
What this badge says. CiteStamped means the CHECKABLE references of this
work were clean at the dated check: each resolved to a known work in a public registry, and none
carried a retraction notice at that time. It says nothing about the quality, findings,
or importance of the work itself, and nothing about references deposited without a DOI.
